Steel Colorful Material Q355 Prefab Building Kits
Prefab metal buildings are customized steel structures manufactured in our factory and transported to your construction site for assembly. All components are precision-engineered to form solid, durable buildings tailored to your specific architectural and structural requirements.
Applications
Our prefabricated metal buildings serve diverse applications across industrial, commercial, and agricultural sectors. They provide ideal solutions for workshops, warehouses, storage sheds, and various civil or commercial buildings. The high degree of customizability ensures adaptation to different customer needs.
Steel Structure Advantages
Steel structures offer significant benefits over traditional wood and concrete construction:
- Excellent strength and durability to withstand harsh environmental conditions
- Flexible design that can be adjusted and optimized for multi-functional use
- Cost-effective with shorter construction periods and reduced labor costs
- Long-term structural security and reliability
Main Structural Components
Our prefab buildings feature precision-engineered components:
- Steel Columns: Vertical load-bearing components that support the entire building structure
- Roof Beams: Horizontal beams ensuring roof stability and structural integrity
- Crane Beams: Specially designed to carry lifting equipment loads in factories and warehouses
- Floor Beams: Horizontal supports for multi-story building floor structures
Secondary Structure Elements
- Bracing: Roof and column bracing for enhanced stability and wind resistance
- Tie Beams: Horizontal members connecting columns and beams for overall rigidity
- Roof Purlins: Structural members supporting roof panels
- Wall Beams: Exterior wall beams for secure wall panel installation
Roof and Wall Panel Materials
Choose from premium materials to meet your aesthetic, insulation, and functional requirements:
- Corrugated Metal Color Plate: Waterproof, anti-corrosion, and durable for standard building structures
- Sandwich Panel: Insulated panels with metal exterior layers for superior thermal performance in cold storage and workshops

Design Considerations
Fire Protection Design
Steel structures require proper fire protection as mechanical properties change with temperature. At 500°C, steel strength reduces significantly, necessitating protective measures.
Fire Protection Methods
- Spray Method: Fire-resistant coatings applied to steel surfaces to increase fire resistance limits
- Cladding Method: Protective layers using silicon-calcium board, concrete, or brick materials
- Water Spray Cooling: Automated sprinkler systems forming protective water films during fire events
Temperature Expansion Joints
Large-scale metal buildings incorporate temperature expansion joints in length and width directions to accommodate thermal expansion and prevent structural stress.
Anti-Rust Treatment
All steel structures receive comprehensive anti-rust treatment with primary and finishing coats. Coating thickness ranges from 100μm for indoor structures to 150-200μm for outdoor or industrial environments.
Key Advantages
Our prefabricated metal buildings deliver exceptional value through:
- Low construction costs and rapid processing speeds
- Fast on-site installation with factory precision
- Modern CNC equipment ensuring structural accuracy
- Significant savings in construction time and materials
- Ideal for workshops, warehouses, aircraft hangars, agricultural storage, and commercial buildings
